Symptom Possible cause Possible solution
The part of the route that the vehicle
has already passed is deleted.
A route is managed by sections between waypoints. If the vehicle
passed the first waypoint, the section between the starting point and
the waypoint is deleted (it may not be deleted depending on the area).
This is not a malfunction.
An indirect route is suggested. If there are restrictions (such as one-way streets) on roads close to the
starting point or destination, the system may suggest an indirect route.
Adjust the location of the starting point or
destination.
The system may suggest an indirect route because route calculation
does not take into consideration some areas such as narrow streets
(gray roads).
Reset the destination to a main or ordinary road,
and recalculate the route.
The landmark information does not
correspond to the actual information.
This may be caused by insufficient or incorrect map data. Updated information will be included in the next
version of the map data.
The suggested route does not exactly
connect to the starting point, way-
points, or destination.
There is no data for route calculation closer to these locations. Set the starting point, waypoints and destination
on a main road, and perform route calculation.
